DESCRIPTION:Anne-Florence Bitbol\nMicrobial populations often have complex
  spatial structures\, with homogeneous competition holding only at a loc
 al scale. Population structure can strongly impact evolution\, in par
 ticular by affecting the fixation probability of mutants. I will first d
 iscuss a general model for describing structured populations on graphs. 
 Then I will show that the specific structure of the gut\, with hydrody
 namics and gradients of food and bacterial concentrations\, can increase t
 he fixation probability of neutral mutants\, with possible consequences
  for the diversity of the microbiota.\n
